Realism should never get in the way of fun.
Yes, things fall apart/break over time or with excessive use. But it still takes way longer IRL for that to happen than in a game with these mechanics. Some of them are really bad and the best equipment lasts for maybe 15 minutes. Which is total bullshit. I don't want to stop the fun part of the game to go back to base and fix my tools every 15 minutes.
